Astronomik OWB EOS Clip-Filter Mini Review

Postby weixing » Tue Feb 07, 2012 11:47 pm

Hi,
This is a quick mini review for those who had mod your Canon EOS APS-C DSLR for Astrophotography or IR photography and feel that the modded Canon EOS APS-C DSLR is quite wasteful since you can't use it for normal photography easily.

I feel the same when I saw my modded Canon 450D in the dry cabinet most of the time and I want to have a backup DSLR if I go Malaysia for photography trip, so I try the custom white balance method on my modded Canon 450D. It's work, but very troublesome as I need to shoot the custome white balance shot once the lighting change. Then I remember that there is a clip-filter for Canon EOS APS-C DSLR that'll bring the white balance back to normal, so I decided to try out the Astronomik OWB (Original White Balance) Clip-Filter.

This Clip-Filter is for modded DSLR which have been converted for Astrophotography or IR use by removing the inbuilt IR-filter or by substituting it with a filter with greater range, so have a white balance that made them not suitable for normal photography. The spectral sensitivity of the DSLR will be changed by the OWB Clip-Filter back to the former range.

The OWB EOS Clip-Filter is very easy to install... just put the Clip-Filter above the depression in front of the mirror and press firmly.

Below are some of the test shots:

For comparison, below is a shot using my normal 60D DSLR:

Advantages
1) Easily switch between normal and modded DSLR.
2) The Clip-Filter will sealed up the internal of the DSLR, so no dust will get to your mirror or sensor when changing lenses.

Disadvantages
1) Viewfinder become dimmer and a bit greenish.
2) Cannot use EF-S lenses as EF-S lenses extend further into the camera.
3) Can only use on Canon EOS APC-S DSLR (Canon 300D and above).

Happy shooting and have a nice day.

Hi Wiexing,

Please correct me if I am wrong.

Isn't the filter fitted behind the mirror? Then how does it affect the view finder image?.
For the same reason how does it affect the usage of EF-S lenses though these have a longer butt compared to EF lenses.
Or does the camera modification involve removal of morror too????? [smilie=confused.gif]

You don't require to mod the modded DSLR again for this Clip-Filter. The Clip-Filter is place between the lenses and DSLR mirror (you can see the Clip-Filter in my second review photo showing my 450D). As a result, the longer butt of EF-S lenses will contact with the Clip-Filter and cannot mount. Check out the below on Astronomik website on how the Clip-Filter is install:

Have a nice day.
